The contactor is a high-voltage relay controlled by your thermostat's 24V signal — when the thermostat calls for cooling, the contactor closes its contacts to send line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common causes of a system that won't respond to a cooling call. Symptoms include the air handler running normally while the outdoor unit stays completely off, visible pitting or burning on the contact points, or a contactor that stays stuck in the open or closed position.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 2-Pole design | 24V coil voltage | Factory-rated amperage for Carrier C4850C50Z2050100 packaged unit | OEM Part Number HN53CB115\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM contactors use silver-alloy contact tips rated for thousands of switching cycles under load.
